Hi Laurent,
  Thank you for picked them up!
But, there are two patches that have not been picked up.
Maybe I should ping the corresponding Maintainer first.

The missing patches are:
[PATCH RESEND v2 2/7] qga/channel-posix: Plug memory leak in ga_channel_write_all()
[PATCH RESEND v2 5/7] migration/colo: Plug memleaks in colo_process_incoming_thread

Thanks,
Chen Qun
